Re: Allcocks Match Aerial Rim-lever check conversion.
Thank you for showing us this excellent adaptation WM+ It's not something that I have the skills nor tools to do myself but I know a man who might

Re: Allcocks Match Aerial Rim-lever check conversion.
Actually....just how do you cut that slot??
I imagine a hole drilled at each end first....maybe a whole series of them joining up, or almost so...but then what?
Don't tell me you've built a plasma cutter or a laser beam...'cos if you do I will, on past experience, have to believe you....

Re: Allcocks Match Aerial Rim-lever check conversion.
I'd imagine the backplate is mounted in the lathe chuck and a small milling cutter is mounted in a motorised toolpost. With a simple indexing attachment it should be quite easy to mill that slotNobby wrote: ↑Sat Jul 06, 2019 1:31 pm Actually....just how do you cut that slot??

Hovis....I wish!
A proper engineer would use a Mill or rotary table I imagine, but there was definitely nothing that I found easy cutting that slot, because the extreme ends of it also limit the rotation of the existing soft alloy cam, the part to which I attached the lever.
I calculated and marked the travel limits with pencil, drilled through first with a 1/16” drill, roughly cut out between them and filed flat with thin, warding files, draw-file finishing with a thin contact breaker file.
It was not possible to use the attachment which I made for the lathe because of the size limitations and necessary overhang imposed by the reel diameter, plus attachment plus chuck plus drill or cutter.
By the way, that attachment is not and never was motorised....it is all very much “handraulic”!
Nobby...lasers are not possible, but am thinking along the lines of spark eroding....

So nothing buy skill and time then! I've seen your "hand cranked" attachment (I think) simple wonderful.
I'm lucky and have a quick release tool post so I turned a holder that fits in the boring bar holder and has an er11 collect between 2 bearings which is held in place by a captive collar. I run this with a flexi attachment to a dremal - crude but workable.

When Leszek says " hand-made" he means hand-made....mostly his hands and some files.

Re: Allcocks Match Aerial Rim-lever check conversion.
Great adaptation and absolutely necessary. I use my ring finger generally, to move the rim lever, whilst trotting.
We were chatting about this on Friday and it’s one of those things you do without thinking about it! Beresford is a little finger operator, apparently!

Re: Allcocks Match Aerial Rim-lever check conversion.
I own one of these 4 1/2" Allcocks match aerials, and indeed, using the original knob is quite frustrating. There are two reasons I do not run and start this rim-lever check conversion: First of all: I would like to keep it original, as it is like brand new, and more importantly, I am unable to do it with my skills

That looks good.
You have a great skill, Leszek.

Re: Allcocks Match Aerial Rim-lever check conversion.
This is great. I love the anti kink line lay segments, where canI get those for my match aerial? Did you make them yourself?
